!!! Overview
[{$pagename}] is the [Digital Identity] presented from Apple's fingerprint scanner on [iPhone] 5S (and we assume later) devices.

[{$pagename}] is an [Authentication Method] which uses a [Biometric Sample] from the Fingerprint which is a [Physiological Characteristic] of a [Digital Identity] and used for [Authentication] and can be defined a [Something You Are] in [Multi-Factor Authentication].

Only a few other smartphone makers have built fingerprint scanning into their phones, as with the Motorola Mobility Atrix 4G in 2011 and several of the Samsung devices. The [iPhone] 5S is the first phone on a major US carrier since then to feature the technology.

In 2012, Apple acquired AuthenTec, a company focused on fingerprint reading and identification management software, for $356 million. Since then, people have expected a fingerprint reading feature.

!! To configure Touch ID
You must first set up a [passcode]. Touch ID is designed to minimize the input of your passcode; but your passcode will be needed for additional security validation:
* After restarting your device
* When more than 48 hours have elapsed from the last time you unlocked your device
* To enter the Touch ID & Passcode setting

[{$pagename}]'s [hardware] is manufactured by [AuthenTec] which was acquired by [Apple Inc] On 27 July 2012 for $356 million[2]!! More Information
